Paleogene

The Paleogene is a geologic period that spans from about 66 to 23 million years ago. It is the first part of the Cenozoic Era, following the Cretaceous Period and preceding the Neogene Period.

Key Events and Characteristics

Climate: The Paleogene experienced significant climate changes, including a gradual cooling trend and the development of modern climate patterns.
Flora and Fauna: The period saw the diversification of mammals and the rise of modern groups of plants, including grasses and flowering plants.
Extinction Events: The Paleogene was marked by several significant extinction events, including the Cretaceous-Paleogene extinction event, which led to the extinction of the dinosaurs.
Geological Events: The Paleogene also saw significant geological events, including the formation of the Himalayas and the opening of the Atlantic Ocean.

Study Guide
